What Is the AR Prosign in Morse Code?
AR is a procedural signal (prosign) meaning end of message. It is sent as the letters A and R run together with no inter-letter gap, producing a single 5-signal sequence.
When you search for “ar prosign in morse code”, “morse code for ar prosign”, or “AR in morse code”, the answer is the same ITU-standard pattern: .-.-.. Other common names for this prosign include end of message, plus sign substitute, +.
When to Use the AR Prosign
Sent at the end of a complete CW message, just before the receiving station’s callsign. It tells the other operator “I have finished my message — over to you (or to anyone listening).”

To transmit the ar prosign (.-.-.), use this sequence:
ITU Timing Rules
- Dot (·) = 1 unit
- Dash (−) = 3 units (3× longer)
- Signal gap = 1 unit
- Letter gap = 3 units
- Word gap = 7 units

How to Remember the AR Prosign in Morse Code
“All Received” — A (·−) plus R (·−·) joined as one symbol means the message is finished and acknowledged-ready.
